Low-Maintenance Living, High Mountain Durability
Composite Deck Installation in Montana
Your Last Deck May Be Your Best
Why More Montana Homeowners Choose Composite
Montana’s weather is unforgiving. Composite decking is engineered to stand up to UV rays, snow, moisture, and temperature swings—without cracking or splintering. These boards require virtually no sanding, staining, or sealing. With a range of colors and grain textures available, composite decking offers the charm of wood without the upkeep. It’s ideal for busy families, vacation homes, and rental properties looking for long-term durability with minimal maintenance.
Performance You Can Seen And Count On
The Composite Deck Advantage
Today’s composite decks are nothing like the early versions. Modern materials blend recycled plastics with real wood fibers for a deck that looks natural but lasts longer. No warping. No rotting. No yearly re-staining. These products are backed by manufacturer warranties—some up to 50 years and we install every board to spec. That means better spacing, fewer callbacks, and clean, safe edges that stay solid for decades.
No sanding, sealing, or staining required
Resists mold, insects, and fading
Made from recycled and sustainable materials
Built for Montana Not Just Anywhere
Our Composite Decks Handle Big Sky Conditions
Not all decks are built for 7,000-foot elevations or high-wind plateaus. That’s why we select materials proven to perform in Montana. From heavy snowfalls in Kalispell to the hot, dry winds in Billings, our composite deck systems are built with regional load specs and footings that won’t shift with frost. We also install heat-resistant and capped composite products that won’t get too hot underfoot during Helena’s summer highs.

Composite Brands You Can Trust for Years
We work with leading composite decking manufacturers like Trex, TimberTech, Fiberon, and Deckorators—each known for durability, style, and strong warranties. Whether you want capped polymer, traditional composite, or high-performance PVC, we help you choose the right product for your climate and budget. Every board we install comes from trusted distributors and is handled by trained professionals who know how to cut, fasten, and seal it for maximum life.
Start to Finish, We Keep It Simple
From Demo to Done We Handle Every Step
Installing a composite deck takes more than just swapping boards. We start with a full site evaluation and remove your old deck if needed. We then prepare the footings and frame for composite-compatible construction, ensuring proper spacing, hidden fasteners, and precise cuts. Our team handles all permitting and leaves the site clean. You get a finished deck that’s ready for Montana’s next barbecue, snowfall, or sunset.
